                        int maxFeatures)
                          throws InvalidExpressionException

Converts the buffer query parameters of DataProvider.

The buffer query parameters of DataProvider include: data source name, dataset name, target geometry object, radius of buffer, condition of attribute query filter, and Attribute field to be obtained. Where the data source name and the dataset name determine a data set object.

Parameters:

dataset - Data set object, corresponding to the FeatureType object in the WFS service implementation.

geometry - Target geometric object.

bufferDistance - Buffer radius.

attributeFilter - Filter condition of attribute quering

fields - The property field to get.

Returns:

WFS Feature query parameters.

Throws:

InvalidExpressionException - When the parameter expression is illegal, the exception is thrown.
